Ford 8N 12 volt conversion, starter solenoid question

Larry48 · Oct 27, 2017

I have an unknown 12 volt conversion on my 8N. The guy mounted a push button starter button on the dash to put 12 volts to the solenoid. I want to use the Ford push switch on the transmission for starting. I need a 12 volt solenoid that I can put 12 volts on one of the 2 small terminals and use the Ford push button switch to ground the second terminal to start it. I can't find diagrams on solenoids and no one in parts stores can talk solenoid coil wiring. does anyone know a solenoid that would work this way?

Echlin part number ECH ST71 available at NAPA and probably a lot of other places. It has 4 connectors; 2 are for the battery and starter and the small 2 are for the isolated operating coil. This can be configured in any way you want it.

Tractor Supply carries a Tisco solenoid with a Ford part number (D2AF-11450-AA) that will do the same job. I'm not a big Tisco fan, so for the price difference, I'd go with Echlin. Whatever you get, make sure it's stamped 12V.

Thanks for that information. K0RFI
